The aim of this study is to analyze the effects of job characteristics of care workers at welfare facilities for the elderly on their intention to change jobs. The study group was a group of care workers at a welfare facility located in OO city, Gyeongsangbuk-do. For the analysis method, we utilized the SPSS program to carry out a frequency analysis, reliability analysis, correlation analysis, t-test, and multiple regression analysis. Research results showed that firstly, there was a significant difference between work characteristics and intentions for changing jobs according to the age of the care worker in the category of skill variety, a subfactor of work characteristics. Meanwhile, there was no significant difference in the categories of task identity, task importance, autonomy, feedback, and intentions for changing jobs which are all subfactor of work characteristics. Secondly, feedback, a subfactor of the work characteristics of care workers, was observed to have a significant effect on their intentions for changing jobs, while skill variety, task identity, task importance, and autonomy did not have a significant effect on intentions for changing jobs. The implications for this study are expected to be used as base line data for finding methods of improvements for the work environment in order to improve welfare facility care workers’ work satisfaction.
